In this study we (1) selected and sampled two onshore and two offshore geological structures within the Cambrian saline aquifer suitable for CO2 geological storage in the Latvian area of the Baltic Region, (2) determined reservoir quality of the Cambrian sandstones prospective for CO2 storage in four structures, (3) estimated storage capacity, (4) studied geochemical, mineralogical and petrophysical alterations of the host reservoir and cap rocks, induced by CO2 storage and (5) provided coupled perophysical and seismic numerical modelling of CO2 plume within one offshore storage site. Our study clearly shows effectiveness of applied time-lapse rock physics and seismic numerical modelling methodology to detect presence of injected CO2 and monitor its evolution in the E6 Baltic Sea offshore structure.
